Profiling GML for RSS/Atom, RDF and Web developers

I spent some time yesterday talking with Ron Lake about GML, RDF, RSS and other acronyms. GML was originally an RDF application, and various RDFisms can still be seen in the design. I learned a fair bit about GML, and about its extensibility and profiling mechanisms. We discussed some possibilities for sharing data between GML, […]

Chris Goad on RDF and GML

RDF versus GML, Chris Goad (Sept 2004), GML is the XML language for geography developed by the Open GIS consortium. The third major revision of this specification, known as GML3, was released in January of 2003. RDFMap, when used in conjuction with RDFGeom, constitutes an attempt to develop an alternative approach based on RDF to […]

geobloggers: “Network Link” in Google Earth

This is the hidden gem of Google Earth. Adding a “Network Link” allows you to fetch KML data from remote servers. It does this in two ways, Time Based or Location Based. So *anyone* can add dynamic data to Google Maps. Apparently KML is based on GML. I don’t know Keyhole/Google’s work differs. There seems […]

geo/photo raw materials from a walk around Bristol

I’ve just been for a walk around town, taking a few photos on the way, with the camera’s clock sync’d to that of my new GPS. I’ve not yet figured out the best tool to use (other than write my own) for hooking up the photo and location metadata. It’s easy enough to get the […]

“Beyond blocking — U.S. and open source censorship slims the Net”, – Newsforge (May 2004)

“ Beyond blocking — U.S. and open source censorship slims the Net“, fairly interesting piece, but mostly entertaining because of the Google Ads for filtering technology that show up (at least now) while reading it. “Easily block Internet content with this new-generation content filter”, “Netmop projects families from pron. Parents too! Works with any ISP”, […]

Happy new year

This site is slowly becoming functional. I’ve upgraded the weblogging software I use here, WordPress, to the 2004-12-31 snapshot which fixes some problems I was having. Have also reinstalled Morten’s FOAF plugin (which also generates SKOS categories from this weblog). The design is the ‘Kubrick’ theme, pretty much without customisation yet. Comments are switched off, […]

Dublin Core “RDF idiom conversion rules” in SPARQL

This note is both an earlybird (and partial) technical review of the new SPARQL RDF query spec and a proposal to the DC-Architecture Working Group for a possible representation language that captures some rules that explain how some different forms of DC relate to each other. As a review, I have to say that I […]
